Warhol died unexpectedly in Manhattan, at 6:32 am, on February 22, 1987. According to news reports, he had been making good recovery from a routine gallbladder surgery at New York Hospital before dying in his sleep from a sudden post-operative cardiac arrhythmia. Prior to his diagnosis and operation, Warhol delayed having his recurring gallbladder problems checked, as he was afraid to enter hospitals and see doctors. His family sued the hospital for inadequate care, saying that the arrhythmia was caused by improper care and water intoxication. His family received an undisclosed sum of money.
